Move examples/*.sx and their expected/ snapshots into per-category subfolders (examples/<category>/...). Folder = leading filename token, with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus runner and LSP sweep now discover each category's expected/ dir, while issues/ stays flat. Example 1058's repo-root-relative companion import is made file-relative. Path strings embedded in 164 snapshots were regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// Variadic heterogeneous type packs — follow-up #2 (generic $R
|
|
// return type).
|
|
//
|
|
// A pack-fn's return type can be a generic name (`$R`) — bound at
|
|
// the call site to match the body's natural type or the caller's
|
|
// target. Today's `monomorphizePackFn` calls `resolveReturnType`
|
|
// which treats `$R` as an opaque struct, so the mono's signature
|
|
// gets a wrong ret_ty and the value is silently zero / garbage.
|
|
//
|
|
// `first(42)` should return 42; the lock-in pins today's `0`.
|
|
// Next commit infers the ret type from the body's tail expression
|
|
// (or first `return X;`) and rebuilds the mono signature.
